      Description

      Performance has regressed significantly with scenes utilizing large textures between 6.1.0 final and 6.1.1 / 6.2.0 snapshots.

      Performance regression becomes significant with larger than the smallest mesh, if texture size is 4096x4096. For example, a test set with 10 Medium models, point light, IBL and no AA is running 16 FPS with 6.2 snapshot and 29 FPS on 6.1 final.
